INTRODUCTION:

Critically ill patients require continuous assessment of their cardiovascular system to diagnose and manage their complex medical conditions. This is most commonly achieved by the use of direct pressure monitoring systems, often referred to as hemodynamic monitoring. The word Hemodynamic monitoring refers to measurement of pressure, flow, and oxygenation of blood within the cardiovascular system. It includes both invasive and non invasive¹.

The word Hemodynamic monitoring refers to measurement of pressure, flow, and oxygenation of blood within the cardiovascular system. It includes both invasive and non invasive.

Values commonly measured include systemic and pulmonary arterial pressure, central venous pressure, pulmonary capillary wedge pressure, cardiac output, and oxygen saturation of the haemoglobin of arterial and mixed venous blood.²

Hemodynamic studies provide wealth of information reflecting the earliest changes in the circulatory system that are not clinically detectable. Hemodynamic monitoring provides information about blood volume, fluid balance and how well the heart is pumping. Current technology allows measurement of central venous pressure (CVP), pulmonary artery pressure during systole and diastole (reflecting right and left ventricular pressures), and pulmonary capillary wedge pressure (pcwp; an indirect indicator of left ventricular pressure)^3.

OBJECTIVES:

1. To assess the knowledge regarding hemodynamic monitoring among staff nurses

2. To assess the practice regarding hemodynamic monitoring among staff nurses

3. To evaluate effectiveness of planned teaching programme on knowledge and practice regarding hemodynamic monitoring among staff nurses

4. To determine the co-relation between pre-test knowledge and practice scores regarding hemodynamic monitoring among staff nurses

5. To find out an association between the pretest knowledge and practice score regarding hemodynamic monitoring among staff nurses with their socio-demographical variables.

HYPOTHESES:

H₁: The mean post-test knowledge scores of staff nurses regarding hemodynamic monitoring who have exposed to planned teaching programme (PTP) will be significantly higher than the mean pre test knowledge scores at 0.05 level of significance.

H₂: The mean post-test practice scores of staff nurses regarding hemodynamic monitoring who have exposed to planned teaching programme (PTP) will be significantly higher than the mean pre test practice scores at 0.05 level of significance.

H₃: There will be a correlation between pre-test knowledge and practice scores of staff nurses regarding hemodynamic monitoring at 0.05 level of significance.

H₄: There will be an association between pre test knowledge scores of staff nurse 1regarding hemodynamic monitoring with their selected socio demographic variables at 0.05 level of significance.

H₅: There will be an association between pre test practices scores of staff nurses regarding hemodynamic monitoring with their selected socio demographic variables at. 05 level of significance.

METHODOLOGY:

A pre-experimental with one group pre test and post test design and quantitative approach was selected to carry out the study. The study population comprised of all staff nurses working selected hospital at Bareilly. The sample size for study was 40 staff nurses.

Non probability, purposive sampling technique was used for selecting sample of the study. The tools used for study were: (i) structure questionnaire to assess the knowledge and practice regarding hemodynamic monitoring. Section I was socio demographic variables, section II was structure knowledge questionnaire regarding hemodynamic monitoring and section III was structure knowledge based practice questionnaire regarding hemodynamic monitoring. (ii) Planned teaching programme regarding hemodynamic monitoring.

Fig:2 Bar graph shows percentage distribution of staff nurses according to their education status

The overall the pre test knowledge mean score percentage is 41.5% whereas in post test knowledge mean score percentage is 80%. The overall the pre test practice means score percentage is 46.66% whereas in post test practices mean score percentage is 83.66%. There was a significant gain of knowledge 38.5% and gain in practice 37 % who were exposed to the planned teaching programme revealing the effectiveness of planned teaching programme (PTP) on hemodynamic monitoring.

The calculated paired‘t’ value (t _cal=64.27) is greater than the tabulated value (t _tab=2.02) in knowledge scores. The calculated paired‘t’ value (t _cal=35) is greater than the tabulated value (t _tab=2.02) in practice scores. Therefore these results proved the effectiveness of planned teaching programme in terms of gain in knowledge and practice scores. The obtained Karl Pearson’s ‘r’ value 0.96 indicates the existence of positive correlation between knowledge and practice score.

The calculated chi-square value for knowledge and practice scores with selected socio-demographic variables revealed that there was no statistical association.

DISCUSSION:

The discussion is based on the data procured from the study” assess the effectiveness of planned teaching programme regarding hemodynamic monitoring among staff nurses.

Maximum nurses i.e. 25(62.5%) belonged to an age group of 20-25yrs, maximum nurses i.e. 24(60%) were females, maximum nurses 30(75%) have completed GNM programme, maximum nurses 19(47.5%) have professional experience between 0 -2 yrs, majority of the nurses 15(37.5%) were working in the ICU, and none of the nurses i.e. 40(100%) undergone in-service education The calculated value of paired ‘t’ value (t_cal=64.27) was greater than the tabulated value (t_tab=2.02).This indicates that the gain in knowledge score was statistically significant at p<0.05 levels. The calculated value of paired ‘t’ value (t _cal=35) was greater than the tabulated value (t_tab=2.02). This indicates that the gain in practice score is statistically significant at p< 0.05 levels.

The Karl Pearson’s correlation value computed between knowledge and practice scores of staff nurses ‘r’ was 0.96.This indicates the existence of positive correlation between knowledge and practice scores. The calculated chi-square value for knowledge and practice scores with selected socio-demographic variables revealed that there was no statistical association.

CONCLUSION:

The study findings concluded that the planned teaching programme on hemodynamic monitoring was effective in improving and acquainting to the current knowledge of staff nurses as evidenced by gain in post test knowledge and practice scores of staff nurses regarding hemodynamic monitoring.

RECOMMENDATIONS:

Keeping in view regarding findings of the present study, the following recommendations were made:

1. A similar study can be conducted on a larger and wider sample for a longer period of time would be more pertinent in making broad generalizations.

2. A comparative study can be done between educational institute and health care institute nurses regarding hemodynamic monitoring.

3. A descriptive study can be conducted to assess knowledge, attitude and practices regarding hemodynamic monitoring.

4. A comparative study can be conducted regarding effectiveness of a planned teaching programme and self instructional module on hemodynamic monitoring .
